IMPROVEMENT IN BARGE-PUMPS.

Specication forming part of Letters Patent No. 143,069, dated September 23, 1873; application led February 25, 1873.

To all whom it may concern:

Be it known that I, CHARLES P. GAVER, of Ashland, in the county of Boyd and State of Kentucky, have invented certain Improvements in Barge-Pumps, of which the following is a'specication:

My invention relates to the combination, with a cast-iron base and plate-iron -tube and spout, of plate-iron valves hinged at opposite sides of the opening in the base-plate, meeting in the middle of said opening, and resting on rubber packing, so as to open inward into the tube and allow a stream of water, the full size ofthe bore of the tube, to enter when the pump-piston is lifted, and to prevent water passing back from the'tube when the piston '1s lowered.

Figure l is a side elevation of a barge-pump embodying Fmy invention. Fig. 2 is a plan of the same. Fig. 3 is a vertical transverse section, showing the valves open.

A is the cast-iron base, having a square hole in its center, around which there is cast an elevated flange, B, and beneath which there are feet c o c c cast to keep the base raised above the ioor of the barge. D is the plate-iron tube, which makes a sleeve-joint with the ange B, whereby the tube D is attached to the base A. E is the spout, which projects over the side of the barge to discharge the Water into the river, 85e. F F are two rectangular valves of plate iron, which are hinged,

one on each of the two opposite sides of the opening in the base A, in such a way as to open into the tube D. G is a ange, upon that they may be able to bear the weight of water above them and not be readily jarre'd to pieces by the sudden descent of the pumppiston.

l use the ordinary one in use in barge-pumps.

The base A, being elevated by the feet c c c c, the Water can flow freely under it. The valves F F, opening against vthe sides of the tube, allow a stream of water the full size ot' the tube to enter the tube D without obstruction from cross-bars, &c., and being of stout plate iron they stand hard Work and last a long time without needing any repairs.

I claim as my invention- The combination, with the tube D and base A, 0i the valves F F and packing H, substanially as and for the purpose hereinbefore set brth.

CHARLES I. GAVER.
